Introduction

ZFS is a file system designed by Sun Microsystems for the Solaris Operating System. The features of ZFS include support for high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, on-line integrity checking and repair, and RAID-Z. ZFS is implemented as open-source software, licensed under the Common Development and Distribution License (CDDL).
ZFS 是一种新型的文件系统，它提供了简单的管理、事务语义、端对端数据完整性以及极大的可伸缩性。ZFS 并不是对现有技术的增量改进，而是数据管理领域的一种全新的方法。我们摒弃了 20 年来的过时假设、消除了源代码的复杂性，创建了一个真正易于使用的存储系统。 ZFS Features • Pooled Storage Model 池存储模型 • Always consistent on disk 在磁盘上始终保持一致性 • Protection from data corruption 防止数据损坏 • Live data scrubbing 实时数据清理 • Instantaneous snapshots and clones 即时快照和克隆 • Fast native backup and restore 快速的本地备份和恢复 • Highly scalable 高度可伸缩性 • Built in compression 内置压缩功能 • Simplified administration model 简化的管理模型 Documents• Open Storage with the Solaris ZFS File System and COMSTAR iSCSI (2009)
